Claims12
A fastener driving tool comprising:
- a housing;
- a fastener driving assembly at least partially positioned in the housing;
- a workpiece contact assembly connected to the housing;
- and
- a fuel assembly at least partially positioned in the housing, the fuel assembly including:
- a fuel cell receiving assembly positioned in the housing, the fuel cell receiving assembly configured to receive a fuel cell and a fuel cell adapter connected to the fuel cell, the fuel cell adapter including a stem and a fuel cell connector connectable to the fuel cell, the stem including:
- a base, a first conical portion directly connected to and supported by the base, a sealing portion directly connected to and supported by the first conical portion, the sealing portion defining an outer domed sealing surface, and a second conical portion directly connected to and supported by the sealing portion;
- and
- a fuel cell receiving block shaped and sized to receive the stem of the fuel cell adapter, the fuel cell receiving block including a stem receiving portion including:
- an outer annular surface, an inner conical surface directly connected to the outer annular surface, an inner cylindrical surface directly connected to the inner conical surface, an inner bottom surface that is annular and that is directly connected to the inner cylindrical surface, and an inner domed surface below the inner bottom surface,
- wherein the inner domed surface of the fuel cell receiving block is configured to engage the outer domed sealing surface of the stem to form a fluid tight seal between the fuel cell adapter and the fuel cell receiving block,
- wherein the inner cylindrical surface and the inner bottom surface of the stem receiving portion are shaped and sized to receive the second conical portion of the stem, and
- wherein the inner bottom surface of the stem receiving portion is shaped and sized to not engage the second conical portion of the stem.
A fastener driving tool fuel cell adapter for a fastener driving tool including a fastener driving assembly, a workpiece contact assembly, and a fuel assembly including a fuel cell receiving block and a fuel cell receiving assembly configured to receive a fuel cell, the fuel cell receiving block having a stem receiving portion including an outer annular surface, an inner conical surface directly connected to the outer annular surface, an inner cylindrical surface directly connected to the inner conical surface, an inner bottom surface that is an annular surface directly connected to the inner cylindrical surface, and an inner domed surface below the inner bottom surface, the fastener driving tool fuel cell adapter comprising:
- a stem receivable by the stem receiving portion of the fuel cell receiving block, the stem including:
- a base,
- a first conical portion directly connected to the base,
- a sealing portion directly connected to the first conical portion, the sealing portion defining an outer domed sealing surface shaped and sized to sealingly engage the inner domed surface of the fuel cell receiving block to form a fluid tight seal between the fuel cell adapter and the fuel cell receiving block, and
- a second conical portion directly connected to the sealing portion;
- and
- a fuel cell connector connectable to the fuel cell,
- wherein the second conical portion of the stem is shaped and sized to be received within the inner cylindrical surface and the inner bottom surface of the stem receiving portion, and
- wherein the second conical portion of the stem is shaped and sized to not engage the inner cylindrical surface and the inner bottom surface of the stem receiving portion when the fastener driving tool fuel cell adapter is received in the fuel cell receiving block.
A fastener driving tool fuel cell adapter for a fastener driving tool including a fastener driving assembly, a workpiece contact assembly, and a fuel assembly including a fuel cell receiving block and a fuel cell receiving assembly configured to receive a fuel cell, the fuel cell receiving block having a stem receiving portion including an outer annular surface, an inner conical surface directly connected to the outer annular surface, an inner cylindrical surface directly connected to the inner conical surface, an inner bottom surface that is an annular surface directly connected to the inner cylindrical surface, and an inner domed surface below the inner bottom surface, the fastener driving tool fuel cell adapter comprising:
- a stem receivable by the stem receiving portion of the fuel cell receiving block, the stem including:
- a base,
- a first conical portion directly connected to and supported by the base,
- a sealing portion directly connected to and supported by the first conical portion, the sealing portion defining an outer domed sealing surface shaped and sized to sealingly engage the inner domed surface of the fuel cell receiving block to form a fluid tight seal between the fuel cell adapter and the fuel cell receiving block, and
- a second conical portion directly connected to and supported by the sealing portion;
- wherein the second conical portion of the stem is sized and shaped to be received by the inner cylindrical surface and the inner bottom surface of the stem receiving portion such that the second conical portion of the stem does not engage the inner cylindrical surface and the inner bottom surface of the stem receiving portion;
- and
- wherein the stem is connectable to a valve of the fuel cell.
